pressure transmitter Summary MAT308 series pressure (DP) transmitter use imported high-quality diffused silicon type, ceramic pressure sensor as sensitive components, use of specific integrated module, precise temperature, zero, full range and nonlinear compensation, to achieve accurate measurement and transmitter the change of pressure on the media such as liquid, gas, steam. Realize the ideal control various places pressure vacuum medium changes such as industrial and mining enterprises, research institutes and other departments. Characteristics dedicated V / I circuit, little devices, high reliability, maintenance is simple, easy, small size, light weight, convenient installation and debugging. alloy shell, three-terminal isolation, electrostatic spray coating, durable. 4-2mA DC two-wire signal transmission, strong anti-interference, long distance transmission. LED,LCD,pointer three kinds of directed header, on-site reading is very convenient. It can be used to measure the viscosity, crystallization and corrosive media. high accuracy, high stability. In addition to import original sensor has been used outside the laser correction, on the machine in the temperature range of integrated temperature drift and non-linear fine compensation, therefore, the use of non-linear small temperature range, high temperature stability.
